CockroachDB

YugabyteDB's sharding, replication, and transactions architecture is similar to CockroachDB in that both are inspired by the Google Spanner design paper. Additionally, both use Raft as the distributed consensus replication algorithm and RocksDB as the per-node storage engine. The following sections highlight the advantages and similarities YugabyteDB has when compared with CockroachDB.

Advantages

YugabyteDB beats CockroachDB in the context of multiple developer benefits including higher performance for large data sizes, better PostgreSQL compatibility, more flexible geo-distributed deployment options as well as higher data density.
